Abstract
PURPOSE:To permit the smooth operation of a valve body by allowing the communication between a chamber formed between the closed edge surface of the valve body and the inner wall of he valve body and the inside of the valve body through a small hole. CONSTITUTION:The body 1 of a changeover valve has a cylindrical form and consists of an inflow part 3, first effluence part 4, and the second effluence part 5. An opened port 6b is formed in the circumferential direction on the peripheral wall of a valve body 6, and a sealing member 7 is formed integrally on the periphery by utilizing the opened port 6b. The sealing member 7 is made thick from the edge part of the opened port 6b towards a communication hole 8, and a projecting stripe 9 is formed, bulging in the radial direction, at the edge part. A small chamber 13 is formed between the upper edge of the valve body 6 and the undersurface of the upper edge wall 1a of the body 1, and a small hole 15 is opened at the upper edge of the valve body 6, and the water pressure which flows from the inflow part 3 balances the pressure on the chamber 13 side with the flow passage side. Therefore, the force pressing the valve body 6 upwardly becomes zero, and the friction during revolution can be reduced.
